Abstract

PURPOSE:To enhance the accuracy of a weighed value and the durability of a weighing apparatus, by dividing a large number of memory hoppers into a plurality of groups and performing combination weighing at every group so as to successively provide time difference. CONSTITUTION:An article to be weighted is supplied to a plurality of pool hoppers 3 in a divided state and the charging wt. is weighed by the measuring hopper 4 under each of the pool hoppers while the weighed article to be weighed is further charged in each memory hopper 6 under each of the weighing hoppers 4 to perform the combination weighing of an approximate wt. to a set objective wt. value. All of the articles to be weighed of a plurality of the memory hoppers 6 provided at every system of each weighing hopper 4 are divided into predetermined plural groups and combination weighing is performed at every group so as to successively provide time difference and the article to be weighed is allowed to pack the emptied weighing hopper 4 and the emptied memory hoppers 6. Because the memory hoppers can be arranged along each system in a multistage system, weighing capacity can be increased without enlarging the apparatus as a whole.

Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention provides a 61st method for approximating the weight of a provider's product to a set target weight value when packaging and providing a product to a consumer, and a method used therein. However, it is related to the device. [Prior Art] Food products such as naturally produced agricultural products and fruits, or confectionery produced in factories, such as snacks, generally have variations in their individual weights. Therefore, when offering these products to consumers, the sales unit is sometimes calculated by the number of units, but it is usually used when packing in bags, etc. Measures have been taken such as setting a target type of ffii and determining a price commensurate with this, or setting a price in advance and packaging with an Ifn commensurate with the price, but in either case, packaging is based on weight. Accurate weighing prior to packaging is extremely important as the weight of the product may vary. In this case, if the fffffl of one packaged product is insufficient, it will lead to the loss of consumer's interests, so it will definitely not be used, so there is no choice but to make some mistakes. As a result, the profit loss on the provider side was not small, and when mass production was carried out, the profit loss tended to increase proportionately. This is especially true when weighing with one h1m device. Therefore, in order to improve the weighing process, it is necessary to divide the product into multiple weighing devices so that the weight value is close to the set target weight value and hang each ff+ffi. Anti-techniques have been developed and put into practical use in which values are appropriately combined to approximate a set target weight value. [Problems with the Prior Art] In such a union U-Kuntan, the material to be collected from the pool hopper of each head is thrown into the Kunk-m hopper, and its Ifi is detected by a heavy-duty unloading device such as a loadrel in the 51-m hopper. However, since the set target weight value is divided into multiple parts as appropriate and the lower part of the weight m value is prepared with a margin, it is not possible to If N heads are prepared, the weight value close to the set target weight value will be divided by 1!7 from among the 2N combinations U.The more heads are divided, the more combinations U. The number of unions increases exponentially, and therefore the accuracy is high when determining the set weight l111 from among the unions U.The equality time (of union U) also increases exponentially, so it ffi Capacity h (decreases).Also, since air cylinders and motors are used to operate each mechanical part of the weighing device, and cams, link cages, and grooves are used, mechanical operations are often difficult. In the old days, where more accurate and high-speed processing was required, each mechanical part was subject to excessive wear and tear, reducing its durability and requiring more maintenance. Even when 10-14 heads were used, it was extremely difficult and rare to perform a 1m measurement that significantly exceeded 100 times per minute.
Since an instantaneous processing method is adopted in which the weight of the object to be ffl or ffl is detected in the 1m hopper and discharged into the hopper after the combination U is discharged each time, one unit of the combination weighing device has a capacity of 1 nicle. There is an unexplored point that it is difficult to take a long time, and in order to use the falling discharge method immediately after the combination Ii calculation, there is a constraint that unless the inclination angle of the collecting chute is made steep, there will be a lot of cooling, which will hinder high-speed processing. Therefore, even if the diameter of the shoe 1- is the same, the height of the force device tends to be higher.゛Next, for example, in a measuring instrument that can hold the combination Z weight value number 14, there will be a combination U of 2' = 16384, but if a combination U is obtained from among these that is equal to or close to the target value, it will be 4.
If there are only 10 groups left...210=1024
(7) The union becomes u. From among these, select the combination as above) and if it is within 4 pairs again, take it out first and fit it into the empty hopper.
The next item can be taken out of 6+4=10 sets by replenishing the ffl item and adding the remainder from the second time. So if there are 5 or more combinations, the remaining 5 = 9.
... 29 = 6 out of 5t2 [If J is rarely used, it will be out of 28-256 according to 14-6-8, and combination 1! It W! lit becomes increasingly unstable and unreliable. However, we have 14 groups, 1 shift, 16 groups, and a total of 61 m.
If you use it all at the beginning, it will be 216 = 6553B, which is usually impossible to do all in the measuring cycle of the measuring device. After that, you don't need to do it, and if you do π1 times on an average (within 6 groups and no less than 10 groups left) = 1 button, you can alternate as described above. Combination weighing, discharging, and replenishing can be performed, and the accuracy and reliability are to a certain degree.This kind of combination 'i!yl m is partially performed and t is J3.This can be called an exchange n processing method. Also, in order to detect the weight of the object to be treated in the 81m hopper, it was done using a load cell, etc.!In addition, high-speed processing was not possible because it was necessary to wait for the shock vibration to decay when the object was loaded into the δ1m hopper. Even if high-speed processing was possible in the combination U performance using one microphone and one computer, such mechanical constraints imposed constraints, so in order to improve this, a so-called memory was installed under the small flange of Mlffl. A combination ilffi based on the above-mentioned cross-7i processing method has also been devised, in which a small brim is provided and the combined activation of each head of the memory hopper is performed during the decay time to shorten the time and achieve high-speed processing. Although it has been put into practical use, it is only done in shifts and is not an overlap process, and in these cases, pool hoppers and 61M
In addition to the hoppers, the memory hoppers are also arranged in a circular arrangement, making it possible to increase the number of memory hoppers.
As devices become larger, the problems mentioned earlier cannot be avoided. Therefore, there is a limit to the number of memory hoppers that can be arranged, although they are basically advantageous. In the above combination Liit m method, 'rf
Instant or alternating 5I as if it were jabeta! ! In order to use the combination U calculation, a certain allowance is set for the set target weight value, and the combination ffl ffi is calculated based on the detected weight.
Once the combination U operation was within the allowance, the subsequent combination U operation was stopped to shorten the required time, but the accuracy of the combination U calculation was that much better! Rareza or previous union U
It was impossible to reduce the number of hoppers used. [Objective of the Invention 1 The object of the present invention is to eliminate the problems of the above-mentioned conventional combination v it m, and to basically install it in each conventional head.

The mold of the δ1m object is distributed from the pool hopper of each series to the cutting Φ hopper connected to the lower side of the pool hopper, and is fed by a mm device such as a load cell that supports an 81 ton small collar.

: Processing for each group can be performed overlappingly to enable high-speed processing. A group of vertically arranged memory hoppers of each series can be formed in the section (by arranging them in a full state, the space inside the collecting shoe 1~ can be used effectively and the center of gravity of the central device can be lowered, and the memory hopper can be arranged vertically). By increasing the number of memory hoppers, it is possible to improve the accuracy of the combination U weighing, and in addition, the difference in height between each memory hopper is reduced to avoid damage to products, etc. In this way, the yield of δ1m products is improved, the quality of the product is not compromised, and the maintenance of the equipment (1!) is performed less frequently, resulting in improved durability. [Example 1] ] Next, embodiments of the present invention will be explained with reference to the drawings. First, the embodiments shown in Figs. A distribution table 1 installed at the top of the frame of the device is supplied with 11Φ objects such as snacks by a conveyor (not shown) and distributed approximately evenly around the table. A pair of parallel arrangement supply feeders 2.2 are installed in four rough radial directions at 90' intervals, and a pool hopper 3 is provided at the tip of each supply feeder 2 facing the pool hopper 3.
A weighing hopper 4 is provided below. and these supply feeders 2. Pool hopper 3.
3 and i-1ffi hoppers 4, 4 are arranged symmetrically in a circular manner with respect to the mold detection part in the center and the hopper opening drive mechanism A, and the 1m hopper 4.4 is formed in a tapered cone shape. The collecting chutes 1 to 13 are connected to the next packaging device, etc., either directly or via a timing hopper (not shown). A pair of vertically arranged vertical port plates 14.14 are provided parallel to the inclined surface of the collecting shoe-1-13 so as not to interfere with the drive mechanism, and are arranged at the inner end thereof. The edges are also provided in such a manner that they do not interfere with each other.Between the pair of support plates 14.1/I, there is a partition wall 11 which is inclined towards the center and is connected to the tapered cone-shaped inner wall of the collection chute 13. As explained in detail by Shun, three stages of memory hoppers 〇, 6, 6 are provided by the discharging plate I-12 which is pivotally supported on the upper part, forming a vertical series with respect to each pool hopper 3 and weighing hopper 4. At the upper end of each memory hopper 6 are upper and lower receiving plates io, which are also pivotally supported as will be described in detail later.
io is provided for each memory hopper 6, and when the upper surface is inclined inwardly, it forms one inclined surface, and when it is oriented toward the discharge plate 9 inside the weighing hopper 4, the two receiving plates 10.10 In the state where the market is stationary in an upward and outward tilted position, the fallen cargo 8 in the t1 ditch hopper 4
Slide the 1Φ object and place it inside the L-to 13.
If the merry hoppers 6 and 6 of the 2.3rd fu are empty, the merry hopper 4 is removed.
When dropping and filling the object δ1Φ that has been moved by h1, the guide is directed upward and inward as specified, and acts as a guide for charging. 6, the weighed material to be covered is fed into the h1Φ hopper 4 with the discharge plate 1-8, which opens and closes outward, being opened. Further, each discharge plate 12, which is pivotally supported on the outer side of the upper end of each memory hopper 6 as will be explained in more detail later, discharges the skewered object held in the inner part 81S in an open state. Released and dropped into the joint shoe 1-13 J: It is covered. The opening/closing mechanism of the receiving plate 10 for each memory hopper 6 is as shown in FIG.
1-A lever 15' is fixed to the outer end of one of the Leebort plates 14 of the shaft 15 loosely supported by the plate 14.14, and a hook pin provided at the upper end of the lever 15' and the outer end of the Naport plate 14. There is a tension spring 15 between
' is provided and is fixed to the shaft 15 and rotates integrally with the shaft 15 to open and open. It is biased to act as a guide for sliding down the weighed material from the straw weighing hopper. A fan-shaped partial pinion 17 is provided at the other end of the shaft 15 via an electromagnetic clutch 16. Also, a slide par 19 having a short rack 18 that meshes with this partial pinion 11 is connected to one rib 1 to plate 1.
The shoes are disposed parallel to the slopes of the inner surfaces of the collecting shoes 1 to 13 and are removably engaged with guide rollers 20 and 20 provided on the outside of the collecting shoes 1 to 13. The structure of this mechanism is substantially the same for the discharge plate 12, which is pivoted on the upper part of each memory hopper 6 and extends downward and outward. Par 19 2nd rack 18
．． 18 is installed in two receivers (pull-in play 1-TO, 10), while the three-tier memory hopper 6.6. The difference is that racks 1B' and 18' are provided.The fan-shaped partial pinion 23, which is pivotally supported on one of the boat plates 1 and 14 via a pin 28, is provided with a receiving plate 10..10. A link 22, which is provided so as to engage with a short rack 21 provided on the upper part of the slide par 19, and which is integrally stepped on the opposite side of the rack 23, is pivotally attached to the frame of the device (not shown) via a pin 25. The tip of the supported swing link 26 is engaged via a roller 27, and the swing link 26 is installed via a gear 17 mechanism to drive the device.
The cam 24 is pushed into the cam groove of the rotating cam 24 so that it can swing freely via a cam follower roller (not shown), and the swinging link 26 moves the link 2 through the roller 27.
2 swings, and the slide par 19 is always moved up and down diagonally through the binion 23 and the rack 21.
Therefore, each receiving plate 10 is opened against the tension spring 15' through the meshing of the fan-shaped partial pinion 17 and the short rack 18 only when the electromagnetic clutch 16 is actuated. ! M objects are dropped and stored in a memory hopper 6 corresponding to S and J. Also, regarding the discharge plate 12 of each memory hopper 6, the Ll-ra 27' is caused by the swinging of the swinging link 26' which swings around the repin 25' as the cam 24' rotates.
As the C link 22' moves in an arc through
A short rack 21 meshes with a fan-shaped partial pinion 23' mounted on the plate 14 via a pin 28'.
', the slider 19' moves up and down in a diagonal direction, and therefore, only when the electromagnetic clamp 16 is activated, the ejection plate 12 is moved via the fan-shaped partial pinion 17 similarly to the receiving plate 1-10 (not shown). The cover is stored in the memory hopper 6 outward against the tension spring! When the electromagnetic clutch 16 does not operate, the memory hopper 6 is always pulled and the spring biases the l11'! It is designed to hold an object to be protected in a posture. In the conventional combination v fft FJi, the number of heads in the device is about 9 to 14, and recently there are 16 heads, but the number of combinations U is U, which is 216, and the number of calculations for the combination is about 210. and the cutting speed is 60 to 8 m min.
When it reaches about 0 times, even if we devised arithmetic processing, it is necessary to check all the unions U at national expense of 1. U)
Perform Torataku and use the set target distance weight value. Measures such as these are being taken. Therefore, to describe the actual number of heads of the combination U operating system of the present invention, the number of heads of each supply feeder 2 is 2 rows for each series, the memory hopper is 3 stages, and the ffl ffi small brim is 1. Since there is one stage of -, there are 32 heads in total, 2 columns x 4 stages x 4 series. Therefore, in Example 6, Union IX! -it m done l
The t value is 232 and 14! There are a huge number of them, and from this, the combination U of the set target weight Φ value or the 1,000 m value closest to it is calculated.
It is almost impossible to do ζ° in a short time on the order of seconds, and it is not necessary. Therefore, what weight value is 10? In order to obtain 1q of the set target weight value or the weight value closest to it, the total number of heads is 32.
Therefore, even if the fraud target is divided into three groups, there will be two left over, and these three groups will be processed separately and independently on a microcomputer and sequentially given time to perform the combination U operation.This group The division is done by placing the small collar at the top and placing three memory hoppers 6, 6, and 6 below it, resulting in four weight values in the vertical direction.
Since weight values are obtained from 8 rows in the circumferential direction, the groups ^1j are mainly divided horizontally in the circumferential direction, taking into account the combination determination and replenishment of the weighing object to the hopper emptied by discharge.
Minimize the number of combinations that are short in the number of combinations and the same rows in the vertical direction, and divide υ1 spatially as much as possible to evenly measure the combinations U. conduct. For example, when performing combination ze at a weighing speed of about 60 times per minute, the calculation time for combination ze is approximately 60 mm seconds, and the calculation time itself is about the same as that of the conventional instantaneous processing method. In the overlap processing method of the present invention, the combination operation by the first group is followed by the second group. The combination operation of the third group is performed, and the result of the combination operation in each group is the overlap ffH that is not subject to correlation U.
n is the combination U of other groups that are successively formed
In order to be able to incorporate it into the calculation, the memory small part or the memory hopper and the 81m hopper that are selected very close to the set target importance value or the set target lff1 value in sequence according to the total Φ cycle are The weighing operation is repeated by refilling the memory hopper that is empty after discharging the weighing object, or the memory hopper and the R1ffl hopper, and repeating the weighing operation.
The i processing time is the number of groups multiplied by 1 noise time, which means that it takes much more time than the conventional instantaneous processing method or alternate processing method, and this extra time increases h1m accuracy. Therefore, the object to be weighed 1 to be fed to the hopper 4 can be sufficiently adjusted during this time, and the number of combinations can be set to more than 10 in one group to increase the total number of combinations U. Then, select the memory hopper or memory hopper and weighing hopper that is closest to the set target weight value or set target weight value, and select the combination U with higher accuracy from the memory hopper or combination of memory hopper and weighing hopper that has the lowest number of memory hoppers or memory hopper and weighing hopper. Select and play! - The durability of viLa can be improved by reducing the number of operations of the opening/closing mechanism of the discharge plate. In addition, in the present invention, since the measurement speed allows a large amount of time to be spent on one processing time, the operations of each group are performed sequentially and in parallel. In some cases, the falling speed sliding speed due to the shape and bulk density of the object, which controls the processing speed, can be processed by adding 1 par to the Klffi speed, and the physical operating time of the drive mechanism etc. Even after subtracting the above factors, we prepare a large number of combination groups and sequentially fi
It can be seen that the Δ-burlap method of the present invention, which performs t ffi, is 1 smaller and has a right advantage. Next, a 61m method according to an embodiment of the present invention will be explained. The material is dropped onto the distribution table 1 to achieve a roughly average weight distribution, and is then supplied to each supply feeder 2. The material to be ffl'li is thrown into the pool hopper 3 from the tip of each supply feeder, and as before, the material is When the weighing hopper 4 on the side is empty, listen to the IR output brakes 1 to 5 and insert the small items to be protected.゛ And in each 4.1 billion hopper 4, the loading diameter j is determined by a heavy M detection device such as a loadrel supporting it.
When the impact has finished attenuating, the input weight is detected, and the detected input weight is input to the microphone [-1 computer and stored as in the conventional case. Then, a control 311 (not shown) electrically connected to the microcomputer controls the diagonal up and down movement of the slider 19 by the cam 24 and swinging link 26 link 22 vinyl A 23 and rack 21. In contrast, the lowest electromagnetic clutch 16 operates and the lowest receiver (
) Only the loading plate 10 is opened, and then the discharge plate 1-9 inside the 81m hopper is heard, and the internal burred material is discharged.
Since it is in a closed state, it slides using this as a guide, and the lower receiving plate 10 is opened.
Then, the receiving plate 10 at the lowest stage is closed by the tension spring 15' as the electromagnetic clutch 16 is disconnected, and the next 1 m object is weighed from the pool hopper 3. In the same way as mentioned earlier, the S
The heavy use of one hanging object is detected and stored as input, and then the upper receiving plate 10 is opened by the action of the electromagnetic clutch 16, and the object is thrown into the middle memory hopper 6, whereupon the next operation is carried out. Due to a failure of the outer output plate 8, 1M of the weighed objects in the mother hopper 4 are filled into the upper memory hopper 6. Furthermore, the protected kumihimo is thrown into the ffl ffi hopper 4, which is finally emptied, from the pool hopper 3, and its heavy pile is detected and stored panonomorily. Therefore, the microcomputer is hi.However, which ff1f is stored in each memory hopper 6 as well as in the hopper 4?
It is stored whether the fffm object of fi value is inserted and held. The above-mentioned weighing, holding and storing is performed for all series. When such an initial state is formed, the first combination itffl starts according to the setting program, but the microcomputer controls not only the itm hopper 4 and each memory hopper 6 of each series but also the horizontal direction as described above. Total 7j: The sleeve 4 and each memory hopper 6 are divided into groups in a predetermined manner, and each divided group is combined as described above through the set time difference. conduct. Then, the hoppers that are excluded from the combination of one group are transferred to the next group and the group I! Continue to assemble. In this case, as mentioned in Hikari, each group (Puru union t!
Since there is a sufficient space between 114 and 114 of each receiving and receiving plate 10, the opening and closing operations of the output brakes 1 to 12 have been performed for a long time, and therefore the opening/closing machine and the groove section move and swing without increasing the speed. As a result, wear and failure hardly occur. and ffl' l hopper 1113J: and each memory hopper 6 that participated in the union U is each discharge plate 9.
゜12, 12.12 is opened by the drive mechanism J5 and the link mechanism and the objects to be weighed selected by the union U are discharged into the collection chute 13 and sent to the next process. Weighing hopper 4 emptied after being transported
For the pool hopper 3 empty J: for the empty memory hopper 6 the corresponding receiving plate 1
0 is opened as mentioned earlier and it is 61m hopper 4.
When the h1 small item that has been ffied is thrown in and it is at the lowest stage, the upper receiving plate 10 is closed, so that it acts as a guide and the small item to be h1 is thrown in. Of course, regarding the memory hopper at the top, discharge plays 1-8 of the 1m hopper 4 will be opened. Regarding input and discharge of the series, in the 61-side hopper 4, by means of both side plates, and in each memory hopper 6, by the report plate 1-14. The object to be weighed is scattered to the side and i! 1 However, it does not cause any errors. Ko. Therefore, the embodiments of the present invention are not limited to the embodiments described above, but as shown in FIGS. Alternatively, as shown in Fig.
The number of heads for combined U-metering can be further sufficiently increased by using the space inside the collecting shoe 1-13 sufficiently effectively, such as by interposing one series of shoes. - In the embodiment described above, if the drive plate of each memory hopper is arranged so that it does not cause interference between the drive side and the memory hoppers, sufficient degree of freedom can be maintained in the setting h1. For example, in the embodiment shown in Figure 6.7, set sheet: 1-1・1
It is possible to arrange the memory hoppers symmetrically or asymmetrically with respect to the center, as long as there is space in the lower space of 3, and is within the scope of design changes. Depending on the structure, it is also possible to increase or remove memory flanges. Regarding the combination U method, it is possible to target both the 1m hopper 4 and the memory hopper 6 as in the embodiment described above, but exclude the 1m hopper 4 and apply the memory hopper 6, 6. 6 only for group v1
It can also be targeted. In this way, it is possible to increase the total number of combinations U by increasing the number of vertically arranged stages in the series of memory hoppers in the output chute, but the combinations cannot be calculated. It is necessary to continuously replenish the weight of the workpiece to be discharged by matching it with the arm cycle, and therefore the required bar 1 mf is required.
iii Roughly increase the number of M hoppers by the number of average combined weight values obtained from the speed of the degree, and leave some margin.
It is important to use words that are important for the production of skewers, and for that reason, there is a limit to how many skewers can be used within this limit.

It is possible to reliably take out 7.12 silk from the armor 1f, 1, and in this way it is possible to take out C3 sets or more than one each. Also, the receiving plate is as described above. In addition to the pivoting opening/closing weight of the embodiment, it is possible to use the slide bar/cutter of the Gunba set.As for opening/closing, various installations can be adopted for )7Iff. Above) In the small example, the 41-ton small collar and pool hopper drive device were used to explain the receiving (pull-in plate). If you manipulate the timing, you can make the closing operation ('?J), and both the opening and closing operations can do what is natural, and the reliability of the IJ cycle can also be improved. Chiro/ν5u F-1 In terms of history, in addition to arranging the series in two rows, it is also possible to arrange only one row at equal intervals around the circumference, and furthermore, each series can be arranged in a circular arrangement. If there is a constraint on the width and force direction, it is possible to arrange multiple rows in consideration of the supply of the work piece to the next process. [Effects of the Invention] As described above, according to the combination method and its combination U device based on the present invention, firstly, the internal space of the collection hopper can be fully and effectively utilized. Although the device is of the same size, memory hoppers can be arranged in multiple stages in each series, and it is possible to virtually provide a large number of heads, as long as the number of training hoppers is not increased. It is possible to greatly exceed the 81 m capacity without increasing the equipment rest, and even if the equipment rest is increased slightly, the effect is that it is possible to increase the total number of large combinations V,000 m liQ. And by doing this, the setting port (for voting (directly Q

Because it does not require high-speed operation at IBP, it is possible to significantly increase the product life without severe attack or punishment, and it is possible to cut light and low bulk material, which was previously difficult. This has the effect of allowing the combination U51 ton to be carried out with high efficiency. In addition, by installing multiple stages of small memory flanges in the collection chute, the center of gravity of the equipment is lowered and stabilized, and vibrations during operation are reduced, which also has the effect of improving the durability of the equipment. Of course the 81ton small size ffl”
Since the head difference between the A hopper and the small memory hopper and between each memory hopper can be slightly covered, the impact of the object h1 during input/discharge 11.1 is small, and the descending distance for one process is reduced, υ As a result, the reduction in commercial value due to destruction of the 61-wide object is reduced, and the yield is also improved.
